G2 Tools & Capabilities (9)
Tool names from Anthropic's directory listing. This server requires sign-in, so we could not read tool descriptions or parameter schemas.
Frequently asked questions
Is the G2 MCP connector read only?
Not entirely. Anthropic's directory sets the permissions field to Read Only and all nine listed tool names read, but the server's own OAuth descriptor advertises two write scopes, research_boards.write and g2_activate.write. G2's documentation goes further and names five research-board tools that create, update, delete, add and remove. The listing is a subset, not the surface.
How many tools does the G2 MCP server actually have?
G2's own documentation tables 21 tools; Anthropic's directory snapshot lists 9. The two sets barely overlap in naming, and the documented set includes vendors, research boards and a buyer intent dashboard that the listing omits entirely. We could not run an anonymous handshake to arbitrate, because the endpoint returns 401 without a token.
Does G2 buyer intent identify individual people?
No. G2's published buyer intent data dictionary defines the unit as the buyer organisation, with company_id, company_name, company_domain, employee count and industry. The only visitor-level fields are visitor_region and visitor_country, which are geography rather than identity. There is no person name, email address or contact record anywhere in the documented schema.
Who is the G2 MCP connector for, a software vendor or a buyer?
Primarily the vendor. Buyer intent is sold per listed product, list_my_products reads products owned by the authenticated account, and G2's usage examples are all sales plays such as account prioritisation and pre-call briefs. A buyer can still read the public catalogue, categories and reviews, but the paid surface assumes you own a G2 listing.
Which G2 MCP tools work on my subscription?
Catalogue, category and review reads are the baseline; buyer intent and competitive data are gated. G2 states that each listed product needs its own buyer intent subscription and that the plan determines which of the nine signal types you receive. Access through partner platforms such as HubSpot and Gong carries the same entitlement dependency, per G2's own limitations notes.
Can I republish G2 reviews that I pull through the connector?
Not on the strength of an MCP token. G2 runs review syndication as a separate partner programme with its own API key issued by a G2 representative and its own endpoints. Nothing in the MCP documentation grants redistribution rights, and reviews carry an anonymous flag that reflects a reviewer choice you must honour.
Why does the G2 MCP server reject my token after a successful OAuth flow?
G2's documentation names a specific cause. The MCP server validates tokens against G2's introspection endpoint using its own server-side credentials, so a 401 after a clean authorisation usually means your OAuth application lacks cross-application token introspection. G2 directs you to contact its platform team to enable it, or to reuse the MCP server's own client_id.
Does the G2 MCP server support dynamic client registration?
No. G2's documentation states its OAuth server does not support Dynamic Client Registration, so you must register an application in the G2 Developer Dashboard and supply a client_id and client_secret. G2 also returns the authorization code without a state parameter, which breaks the default MCP TypeScript SDK callback handler until you relax it.
What are the G2 API rate limits for the MCP server?
One hundred requests per second, globally. G2's MCP documentation states the underlying G2 API enforces that limit and that exceeding it blocks access for 60 seconds before requests resume. The MCP server sits on the same API and inherits the same ceiling, so a fan-out agent loop is the realistic way to trip it.
